Show HN: Go Memory Visualizer, real-time struct layout and auto optimization

Hey HN! I built a VS Code extension that shows you exactly how Go lays out your structs in memory and automatically fixes padding waste. What it does: Inline annotations showing byte offsets, sizes, and padding as you type One-click optimization that reorders fields to eliminate waste Diverse-architecture support (amd64, arm64, 386) Hover for detailed memory layout info Why it matters: Poor field ordering in Go structs commonly wastes 10-30% of memory due to alignment padding. For example, a careless 56-byte struct can become 40 bytes just by reordering fields. At scale, this adds up — both in memory costs and cache performance. Demo: Before: 56 bytes After auto-optimization: 40 bytes (-29%) The extension highlights wasteful padding in real-time and offers a CodeLens button to fix it automatically.

GitHub: https://github.com/1rhino2/go-memory-visualizer https://github.com/1rhino2/go-memory-visualizer Built this after repeatedly optimizing structs manually in production code. Figured others might find it useful too. Would love feedback on what other memory-related features would be helpful!
